Soil Confrence at UFS
At the Combined Congress with the theme ‘Basic and applied sciences – Fundamentals of sustainable agriculture’, were from the left: Prof Klaus Kellner, Prof Prakash Naidoo, Dr Cobus Botha from the Agriculture Research Council, Prof Vaughan Hattingh, and Mr Matome Ramokgopa.

“We are at the beginning of a new decade that will in all likelihood be pivotal for aspects such as food security, climate change, and the sustainable use of natural resources – aspects that the societies you represent are of course keenly involved with – and in terms of which you can play an increasingly valuable role.” 

These were the words of Vice-Rector: Operations at the University of the Free State (UFS), Prof Prakash Naidoo, on opening a Combined Congress of the Soil Science Society of South Africa (SSSSA), the South African Society of Crop Production (SASCP), the Southern African Weed Science Society (SAWSS), and the Southern African Society for Horticultural Sciences (SASHS).

The UFS Department of Soil, Crop and Climate Sciences is hosting the congress, with scientific content of four disciplines (soil, crop, weed, and horticulture) presented by both local and international guest speakers.

The theme of this year’s congress taking place on the UFS Bloemfontein Campus, is Basic and applied sciences – Fundamentals of sustainable agriculture.

Prof Naidoo continues: “It has been predicted that the world will need almost double the current food supply by 2050 to feed an ever-increasing world population. This clearly makes the scientific work done in the agricultural sector and the organisations affiliated with it, more vital than ever. We need to do what we can to ensure food security and sustainability.”

“A congress like yours is an opportunity to tap into the perspectives and research results of collaborators from different fields, and from different levels of skill and experience – with the aim of ultimately benefiting wider communities.”

Leader in agriculture sector

Prof Vaughan Hattingh, representing SASHS (Chief Executive Officer of Citrus Research International); Mr Matome Ramokgopa, representing SASCP (General Manager of Enza Zanden SA); and Prof Klaus Kellner, representing SSSSA (Department of Botany at the North-West University), delivered the combined opening address.

Prof Hattingh, speaking on ‘Industry–University partnership opportunity road ahead for horticultural research’, says citrus is a major horticultural product internationally and the biggest horticultural export from South Africa. The citrus industry, the second largest exporter of citrus in the world, generates R20 bn per year and is the biggest funder of research in this area. 

Prof Hattingh states that university partnerships, developing science to assist the industry, are key. “The future of horticultural industries and horticultural research at universities depends on successful university-industry partnerships.”

Mr Ramokgopa talked about ‘Innovative solutions for vegetable seed production for a growing population’, saying that Enza Zanden employed several techniques in vegetable production in response to the needs of retailers and consumers. These include smaller tomatoes (for snacking purposes), smaller leaf size of lettuce (thus a smaller area for decay), plastic-free packaging of cucumber with a longer shelf life, and more uniform onions (suitable for onion rings). 

Prof Kellner focused on ‘Scientifically sound policies and practices to ensure food security and sustainable agriculture’. He said: “It is getting warmer in Southern Africa and Europe. We need to realise it and adapt practices accordingly.”

More discussions on sustainable agriculture

Other interesting topics covered at the congress include, ‘Developing propagation technologies for indigenous plants used in the natural products industry’; ‘The influence of foliar and application rate of nitrogen fertiliser on seed and oil yield of canola’; ‘Sweet potato production in sacks: potential utilisation of limited space in rural, urban and peri-urban areas’; ‘The efficacy of postharvest wax application in the reduction of chilling injury incidence in lemon fruit’; and ‘Herbicide use within the commercial forestry sector in South Africa’.

Congress attendees can also look forward to the ‘Soil fertility and crop nutrition symposium: principles and practices’ on Wednesday 22 January 2020.

The congress kicked off on 21 January, and will come to an end on Thursday 23 January 2020. For more information on the sessions, see programme.

Good quality wheat essential for bread production

“Wheat quality, specifically grain protein, is of the most crucial components determining the profitability of wheat farmers.”

This is according to Robbie Lindeque, wheat breeder at the ARC Small Grain Institute in Bethlehem. As a wheat breeder, one of his primary aims is to make a contribution to sustainable wheat production in the inland of South Africa.

A closer analysis of bread wheat protein

With his PHD thesis, "Protein quality versus quantity in South African commercial bread wheat cultivars”, Lindeque answered critical questions regarding the South African wheat industry. The major question of his PhD, which he received on 30 June 2016, was whether protein quality could compensate for protein quantity as a measure of bread quality in South Africa.

The three main wheat-producing areas in South Africa, the dryland summer rainfall region (Free State), dryland winter rainfall region (Western Cape), and the cooler irrigation regions (Northern Cape), were used as a starting point for the study.

Proteins are essential for the baking of good quality bread. Worldwide, the utilisation of wheat flour shipments in the baking industry is determined by the protein proportion of the shipment.

Lindeque says the aim of his thesis was to determine whether a closer analysis of bread wheat protein would provide a better indication of good or bad bread quality. “The conclusion from this study was that both protein quantity and protein quality from all three production areas in South Africa varies constantly in accuracy regarding the estimation of bread volume, mainly as a result of environmental factors,” says Lindeque.

Results relevant to the wheat industry

In 2012, application was made to the Winter Cereal Trust for funding of the project. After funding was approved – thus making the Winter Cereal Trust the main partner – seed samples were collected from the 2012 and 2013 national cultivar adaptation trials.

“After this, the seed underwent protein and flour analyses, which added a third year to the study, with the fourth year consisting of statistical processing and documenting of the results,” says Lindeque.

Funding by the Winter Cereals Trust contributed to the fact that the study constantly attempted to keep issues and results as relevant as possible to the wheat industry.
